HYDRoCARBoN-BURNER.

SPECIFICATION forming part of Letters Patent No. 765,027, dated July 12, 1904,

AApplication filed May 26,1902. Serial No, 109,106. (No model.)

To a/ZZ whom it may concern:

Be it known that I, ROBERT MATHEsoN, residing at San Diego, in the county of San Diego and State of California, have invented a new and Improved Hydrocarbon-Burner, of which the following is a specification.

This invention is in the nature of an irnproved means for vaporizing distillate oil and converting same into a gas in an economical, convenient, andv effective manner; and in its general arrangement the said'invention comprehends a novel construction of generating means, including a converter adapted to project into the stove or other casing in which the burner is held for the usual purpose, a jet-pipe forming an attached part of the converter, and a supplemental vaporizing means for initially heating the main converting or generating devices.

In its more complete nature my invention embodies a converting or generating chamber slidable within the stove or I casing body, a jet-pipe for operating with said chamber at a point within the stove or casing, a valve-feed for the front or exposed end of the generating-chamber, and a residuum collector detachably held within the converting or generating chamberand slidable into and out'l of the exposed end thereof, it also including a special arrangement of plugs in the jet or vapor-conveying pipes to provide for conveniently cleaning out the said pipes without the necessity of disconnecting them from each other or from the generating-chamber.

In its still more subordinate features my invention consists in certaindetails of construction and peculiar combination of parts, all of which will hereinafter be fully described, and specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure 1 is aside elevation of my invention, a portion of the stove-casing being shown to the more clearly illustrate the general arrangement of my invention. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. l. Fig. 3 is'a vertical longitudinal section of the same on the line 3 3 of Fig. 2. Fig. 4 is a horizontal section of the same on the line t I of Fig. 1. Fig. is adetailview of the residuumcollecting pan, hereinafter described. Fig. 6 is a cross-section of a modified yform of the generating-chamber, hereinafter referred to. In the practical construction my invention comprises an elongated, preferably rectangular, casing l, which forms what I shall hereininafter term thev generating-chambci" or converten as the oil in its passage therethrough is converted into a gaseous vapor. This casing when operatively applied to a stove, fire-pot, or other heat-collecting casing is projected into the casing S through a suitable openings in one end thereof, and the said converter l extends inwardly nearly the full width of the said casing S, as clearly shown in Fig. l, by reference to which it will also be noticed one end of the casing 1 has an outwardly-projecting portion la, open at its outer end for a purpose presently explained, and an opening designated by 1b is normally held closed by a screw-cap 1c. 2 represent-s the oil-feed pipe, which is provided with a needlevalve 22l of any approved construction, and the said pipe joins with the end 1a of the body 1, as shown.

A vapor-olftale pipe 3 communicates with the generating-chamber 1 inside of the stove body or casing, passes rearwardly over the top of the said chamber, and joins through an elbow union-coupling 3 with the pendent pipe-section 3b, which joins by the elbowcoupling 8 with the lower or burner pipe 3, disposed in a horizontal plane under the generating-chamber, and the said pipe 3d has a numbery of dischargingjet-nozzles. The discharge-orices are proportionate to the size of the generating-chamber, whereby to permit of a free flow of gas as fast as generated, and to reduce friction the bottom or threaded portion of theV jet-nozzles are counter-sunk at a point near their outlet, and the said nozzles are also slightly countersunk on the top (see Fig. 3) to conveniently aid in cleaning the said jet-nozzles'. To provide for conveniently cleaning the pipes 3, 3b, and 3d, the elbow-couplings 3 and 3c have plugged openings Sfg, as shown, and so arranged that by the removal of said plugs a cleaning-brush or other implement can be readily inserted into said pipes.

to the base member :v ot' the stove-body and.

held to straddle the pipe-section 3 and hold same, with the sections 3" and 3, in a proper position relatively to the converter 1.

7 designates a supplemental vaporizing means consisting of a burner-pipe 7, disposed parallel with and adjacent the main burnerpipe 3d and 'provided with a number of jetnozzles 7", and said pipe seats in an oil-trough 8 and joins by the pipe connections 7c 7 l with the valved oil-feed pipe 7 e, as shown.

9 designates a sheet-metal U-shaped pan, slidable into the open end of the convertingchamber l. This pan extends the full length of the chamber l and serves to collect all the deposits or residuum within the said chamber, and by reason of such arrangement of parts the entire deposits within the chamber l can be conveniently removed by drawing the pan 8 out of the open end of the chamber l in a manner clearly understood from Fig. 3 of the drawings.

By providing a converting or generating chamber as described an important advantage is resultant thereof, as the pan, with the residue, can be easily removed without disorganizing any of the other parts. A formidable obstacle is thereby overcome, since asphaltum and other residue of oil when incrusted is hard to remove. In practice the pan 9 is made oil-tight to prevent oil from flowing into the generating-chamber between the pan and walls thereof. i

By extending one end of the generatingchamber through the end of stove feed-pipe connections can be conveniently made and the generating chamber or converter easily cleaned without removing the same from the stove.

By making the generating-chainber of a length to extend approximately the full width of stove-pot admits of the burner-pipe having a plurality of gas-jets, and thereby provide a iame the full width of the lire-box, with the result that the flame is evenly distributed throughout the stove or range, as the case may be.

In operation distillate or low-grade oil is irst fed into the supplemental vaporizing burner-pipe and a quantity or' oil permitted to accumulate in the oil-holder` in which the said supplemental burner seats, which is then forced to heat the said supplemental burner suicient `to generate gas in the said burner,

the jets of which discharge against the main generating devices. This in practice usually takes about three minutes, after which the oili'eed to the supplemental bu'rner is turned ofi', the oil remaining in the said supplemental pipe being sutcient to supply gas enough to heat the main generator. After the latter is sutiiciently heated oil is turned into the chamber l, which immediately becomes vaporized and passes into the oiftake or burner pipe 3d. The supplemental vaporizing means are not used after the main generating means are started.

Thile I prefer to arrange the several cooperative parts as shown, they may be varied and modilied in their detailed arrangement without departing from the scope of the appended claims. For example, instead of mal;- ing the generator l of a square shape in crosssection, as shown in Figs. l, 2, and 3, the same may be made triangular or cross-shaped, as shown in Fig. 6, and while I have not shown it when the latter form of the generator is used it is preferred that the feed-pipe 2 discharge into the top of the generator instead ot' at the side, as shown in the construction illustrated by Fig. l.

The advantage in having the generatorchamber made trough-like. as shown in Fig. 6, is that it increases the inside area of the generator and also provides for obtaining the full benelit of the flame by reason of the said iame striking the inclined sides of said generator, and by having the pipe enter at the top the same will not interfere with the removing-pan.

I-Iaving thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A hydrocarbon-burner, comprising in combination, with the lire-pot, a vaporizing-chamber, consisting of the closed casingheld within the tire-pot and having a portion extended outside the pot, a removable closure Jfor said extended portion, a collecting-pan within the chamber, an oil-feed communicating' with the said casing, an otttake also communicating with the casing, said otftake including an upper horizontal pipe-section, a lower horizontal pipe, a vertical pipe, elbows connecting' the vertical pipe with the horizontal pipes, and having hollow members extended beyond the lire-pot casing provided with removable plugs, the horizontal pipe having jet-burners held to discharge against the casing, and means for initially heating the said casing, substantially as shown and for the purposes described.
